A maths tutor that checks the working—not just the answer.
Work through real Edexcel papers on one screen. Every submitted line is tested, mapped to the official mark scheme and used to choose the smallest useful hint.
dy/dx = 2x − 2 − 12/√xExact derivative confirmed. The next step is ready.
Mathematics verifies the step.Equivalent correct forms are accepted where the checker can prove them.
The official scheme awards the marks.M, A and B points remain separate and dependencies are preserved.
Hints teach, rather than reveal.You get time to self-correct before one carefully chosen clue.

Every question is paired with its official mark-scheme section. All 56 questions have complete step-aware routes. Symbolic and numerical work is checked mathematically, written reasoning uses reviewed contracts, and visual and judgement marks stay in an honest guided-review lane.
